    • A nestable merchandise cart including a rear frame and hinged side frames which pivot outwardly until limit stops are engaged, and a movable shelf which, when in place to support a load, locks the side frames into positions generally perpendicular to the rear frame. The shelf can be raised and stored, which releases the side frames to pivot outwardly and form a tapered nest into which a like cart will fit nestingly. The side frames may be biased outwardly by springs and pivot outwardly automatically when the shelf is raised, and may also pivot inwardly against the rear frame to a collapsed position suitable for high density packing and shipment of the cart.
    • 一种可嵌套的商品推车,包括后框架和铰接的侧框架,其向外枢转直到限制止挡件接合;以及可移动搁架,当在适当位置支撑负载时,将侧框架锁定到大体垂直于后框架的位置。 搁架可以升高和储存,这释放侧框架向外枢转并形成锥形嵌套,类似的手推车可嵌套嵌入其中。 侧框架可以被弹簧向外偏压并且当搁架升高时自动向外枢转,并且还可以相对于后框架向内枢转到适合于高密度包装和推车的折叠位置。

    • An improved vehicle is provided in the form of a wheeled transport cart which may be towed in a train of similar carts for transporting groceries, or other commodities, around a warehouse, or the like. The transport cart of the invention is constructed with a hinged bottom which may be turned up when the cart is empty to permit the cart to be nested with similar carts when not in use so as to conserve space. When the bottom is turned down to receive a load, one of the wheels or casters is locked in a particular angular position to prevent the cart from zig-zaging or drifting when it is towed.
    • 一种改进的车辆以轮式运输车的形式提供,该拖车可以在类似车辆的列车中被拖曳以便在仓库等周围运送杂货或其它商品。 本发明的运输车辆构造有铰链底部,当手推车为空时,该底部可以翻转,以便在不使用时可以使用同样的推车来推车,以便节省空间。 当底部向下转动以接收负载时,其中一个轮子或脚轮被锁定在特定的角位置,以防止推车在被拖曳时进行起落或漂移。

    • A security cart includes a rear wall, a wheeled base frame connected to the rear wall and a base shelf pivotable between a horizontal position and a raised position. A first sidewall and a first door pivotally connected to the first sidewall are movable from locked positions with the base shelf to a folded position forwardly of the rear wall. A second sidewall and a second door pivotally connected to the second sidewall are movable from locked positions to a folded position forwardly of the folded first sidewall and first door. The base shelf is movable from the horizontal position to the raised position, and retained against the folded first sidewall and the first door and the folded second sidewall and second door.
    • 安全车包括后壁,连接到后壁的轮式底架和可在水平位置和升高位置之间枢转的底架。 可枢转地连接到第一侧壁的第一侧壁和第一门可以从与基架的锁定位置移动到后壁向前的折叠位置。 枢转地连接到第二侧壁的第二侧壁和第二门可以从折叠的第一侧壁和第一门向前的锁定位置移动到折叠位置。 底架可从水平位置移动到升高位置,并且保持抵靠折叠的第一侧壁和第一门以及折叠的第二侧壁和第二门。
